Don't give up!
Well Ironsides, it doesn't look like I'll find a solution for the LNB issue I have with the DMX242. Nobody so far has been able to duplicate my problem. I'm not stupid, I'm not a newbie and I've never had this problem before installing the 2 new DMX242 lnb's, go figure. I just don't know what to believe anymore. Maybe there's a defect in a batch of the DMX242's that they haven't caught. Manufactureres sometimes change sources of components from time to time and maybe other changes too but haven't associated any issues with the changes in production. It's only a guess as to what this is. I've exhausted every test method and all of my 22khz switches and it costs money. I should have gone with my gut feeling and spent a few extra dollars and bought GEOSATpro lnb's.
They can't duplicate the problem because they don't have your Lnbfs or setup. In order to duplicate they would need an exact setup, I would think. Before giving up, Maybe you could talk with Robbie and come to arrangement to ship those lnbfs back to him and maybe split the costs or something. If he can get the lnbfs back maybe they can test and see what is going on. Blowing 8 22hz switches had to be expensive and shipping is expensive but maybe you guys can work something out.
It would be in his best interests to resolve the issue now before it turns into a much larger issue with other buyers. I am sure he would work with you and try to resolve it. It would also be good for other members here to follow along with the testing so we can all learn something.
From what I've read my guess is the lnbfs you have are the problem but that's just my opinion. From my own problems with the DMX 741 install and what happened with my tests I concluded that I had one of 4 problems, Coax or the length or the lnbf itself. Or perhaps Polarity.
I ruled out the coax and length because it works fine with other lnbfs and all my receivers.
I tested every receiver I have, Pansat 2500, Pansat 2700, Dreambox 7020, Dreambox 500 and a Twinhan DVB card. I also tested it on a Neusat, the Neusat is the only receiver I can get to work correctly on that lnbf at this time. Latest test has been with the Pansat 250SM and it hardly sees any channels on either C-Band or Ku. I can stick it on my Primestar dish and test it on one of the same ku band satellites I tested prior and it scans in almost all the channels. It does miss a few but dude, not nearly as many as it does when connected to the 741....Actually the 741 has a better Q than my Primestars...
I still need to test the polority issues and see what happens.
Point to note, Don't give up, the answer is out there and it could be something very simple or just a defect. You have went the extra mile on your part and the great expense in both time and equipment. Perhaps due to that fact Robbie would be willing to help with the costs of shipping them back to his lab so they can test. If they find faults maybe he can offer some replacements and replace those bad 22 hz swithes.
It would be interesting to see the results...
Also I don't think anyone within reason would question your abilities, your dish farm speaks for itself in a huge way. That took a great deal of knowledge to aquire and setup and maintain! Anyone with half a brain wouldn't question that! Your replies here on the forum speaks for themselves! Dude you are the man when it comes to FTA! You speak in simple language often times I have no idea what someone else is talking about and you'll come along an explain things and it clicks. I've read a lot of your posts where you are trying to explain or help someone who has troubles, You don't over complicate it, you just get to the point and explain it in a way a newbie can understand! That says a lot right there IMHO!
